In a new report, Kosovo: The Challenge of Transition, the International Crisis Group urges Martti Ahtisaari and the UN to "prepare for the possibility of imposing an independence package for Kosovo, however diplomatically painful that may be in the short term", as "it is extremely unlikely that any Serbian government will voluntarily acquiesce to the kind of independence, conditional or limited though it may be, which is necessary for a stable long-term solution."
